HEATING APPARATUS.

Specification of Letters Patent. PfltQllfe (l 1 3 1917 Application filed April 8, 1916. Serial No. 89,904.

Allegheny and State of Pennsylvania, have invented a new and-useful Improvement in Heating Apparatus, of whichthe following is a specification.

This invention relates to apparatus for heating ainlventilating buildii'igs. The object of the invention is to provide apparatus which constantly renews the air in the room tor purposes of ventilation and which nevertheless may be regulated to maintain an even temperature regardless of the tcmperature oithe external air. More specifically, the invention has relation to so-called indirect heating apparatus, in which a current of external air is'passed over or around radiators to increase its temperature and is then discharged into the room or space to be heated or ventilated.

The invention comprises the apparatus hereinafter described and more particularly pointed out in the claims.

In the drawings, which represent one embodiment of the invention, Figure 1 is a front elevation with the front wall of the casing or jacket removed to expose the interior parts: Fig. 2 is a side elevation, with the side wall removed: Fig. 3 is a horizontal section on the line 3-4-3. Fig. 1: and Fig. &

is a detail view, on a larger scale. and illustrating the controlling valves or dampers.

Briefly stated, my improved heating and ventilating apparatus comprises a casing or jacket to be located in any suitable place in or on the walls or floors ot' a building and provided with con'imunication to the air out side. of said building and also to the room or space to be heated and ventilated, and within which casing or jacket are located one 'or more radiators and an air fan or pump for circulating the air over or around the radiators into the room. E v

Referring to the drawings, the outer casing or jacket, indicated at L may be made of sheet metal or-.other suitable material in any desired shape or form. Intermediate its top cross wall 2 dividing the space in said casing into a pump chamber 3 and a heating chamber 4. The bottom'jofi the casing is closed l a floor or base 5, which may rest on a suitable support. and in turn supports the motor and pump.

and bottom it is provided with a The pump chamber 3 is provided on one. side with an opening communicating with a pipe or conduit (3 having a valve or damper 7 therein and leading to the outside of the building and through which the fresh air supply for ventilation is drawn. \Vithin' said chamber is a tan or pump 8, shown as a centrifugal pump, whose inlet S) is open to the pump chamber opposite pipe 6 and whose axis coincides with the axis of the pump rotor. The pump is driven by any suitable power source. such as the electric motor 10, its outlet 11 being at its top through wall :2, preferably' near the center thereof, whereby the air is delivered to the heating chamber 4 beneath the radiators therein. i

In the heating chamber are. located one or more suitable radiators 12, made up of sections banked in rows, as is usual, and separated by spaces 12 to provide free air circulation tor tempering the air. Said radiator sections are connected to each other and to manifolds or supply'pipes ltfor circulating or expanding the heating medium, such, as steannhot 'ater or the like therein.

Above the radiators is a cross wall 15, provided with a large number of perforations tor-retarding the air flow and causing the steam to spread unifm'mly over said plate and become thoroughly mixed to temper it and produce a uniform temperature.

Above the cross wall 15 is a suitable outlet to the room. such as an arched top having a curved back 16 and whose tront portion opens at 17 into the room or space to be heated. The outlet 17 may, however, be in the floor. in which .case no archedftop is necessary, as will be readily understood. The -curved back deflects the air current outwardly into the open room, and the dis charge opening 17 may be protected and partially covered in any suitable manner by an ornamental grating 18, as will be readily understood.

In the apparatus shown in the drawings the pump outlet 11 is located at or near the center of the heating chamber. so that'it is directly beneath the radiators therein. Suitable means is provided for controlling the flow of the air current through or around said radiators. so as to regulate the temperature ot the air current finally discharged into the room. For this purpose the heating chamber is provided with a series of dampers or valves located below the radia tors. and over the pump outlet 11, said dampers being arranged in two sets located respectively in a horizontal wall 19 and two "vertical walls 20. Wall 19 is co-extensive with the horizontal area occupied by the radiator sections, and as the latter onboth sides are spaced from the walls of the casing or shell, the edges of said wall 19 are spaced from the shell or casing. The vertical walls 20 extend downwardly from the edges of the wall l9and upwardly, along the sides of the radiators, so that open channels or spaces 21 are left between the side walls of. the outer casing or shell 1 and the walls 20.

In the cross wall 19 are located a series of long narrow valve plates or. dampers 22, hinged at 23 and arranged somewhat like the leaves of -a window shutter. Part of said plates swing downwardly in one direction and part in the other, as shown. The vertical walls 20 are provided with similar dampers or plates 24. Suitable operating means is provided for operating all of said plates in unison, the arrangement being such that movement of the operating member in one direction opens the horizontal plates and closes the vertical plates, while move- 'ment in the opposite direction closes the.

horizontal plates and opens the vertical plates. As shown, the free edges of dampers 22 are pivotally connected to rods 25, having arms 25 rigidly connected thereto, and the free edges of dampers 2l.are pivotally 35 connected to rods 26 having arms 26 rigidly attached thereto. Arm 25 has solidly connected thereto an extension 25hpivoted to a link 26 pivotally connected to the arm 26 The arms 25 are pivotally connected by links 27 to two arms31 on a shaft 32 passing through the casing and having an operating handle 33 on. its outer end.

' By rotating shaft 32 the'links- 27, '28 com municate motion to the two sets of horizontal and vertical dampers or valves, which,

, however, receive reverse motion, as described.-

All of the air supplied by the pump 8 passes into the space beneath'the-wa'lls 19 and 20 from which it issues to the open and does not require its temperature to be raised to such a -high degreethe horizontal.

dampers are more or less closed and the vertical dampers more or less opened, so that part or all of the air flows into the channels 6r open spaces 21 on the outside of the radiator sections and is'consequently not heated thereby. At the upper ends of said chan- Consequently all of nels 21 .are curved plates 29 which deflect the two side air currents inwardly to be mixed with the warmer air flowing past the radiators. The horizontal perforated plate 15 above the radiators chokes back the air currents and distributes the air over the entire area of said plateand thoroughly mixes and tempers the air and gives it an even temperature over the entire stream. The

plate 15 is preferably located a little above the deflectors 29 to provide-open spaces 30 therebetween through which air flows outwardly toward the side walls of the casing,

as indicated by the arrows A, thereby avoiding dead air spaces above the deflectors 29.

By properly regulating the positions of the two sets of dampers and thereby dividingthe air current to cause more or less thereof to contact with the radiator sections an even temperature may be produced irrespective of the temperature of the outside alr.

What I claim is: 1. A unitary heating and ventilating apparatus comprising a housing having an inletopening adjacent its bottom and a discharge opening near its top, heating radiators located at an intermediate point within said housing and arranged so that air may, be" forced through and over the same, said housing being provided with passages around the radiators, means within the housing arran ed to draw air from the inlet opening and orce it over the radiators and through the passages to the discharge opening, means for controllingthe passage through and over the radiators, and means for controlling the entrance to the passages around the radiators, both of said latter controlling meansbein operable in unison, wherebythe relative ow .of air over the radiators and through the passages may be regulated.

2. A unitary heating and ventilating apparatus comprising a housing having an inlet opening near its bottom and a discharge opening adjacent its top, heating radiators located at an intermediate point within said housing within a passage therein, a series of horizontally located dampers controlling the entrance to said passage, said housing being provided with a'plurality of passages around said radiators, a plurality of vertically located dampers for controlling the [entrance to said last named passages, allof .said dampers being arranged to, be operated in unison, whereby the relative flow of air over and around the radiators may be regulated.

3. Heating and. ventilating apparatus,- comprising a shellor casing opening into" air between said radiators and the other of which controls the flow of air around the same. 7
